Electric vehicle having scene identifying function

Abstract

The invention provides an electric vehicle having a scene identifying function. The electric vehicle comprises an electric vehicle body and a scene identifying module disposed on the electric vehicle body. The scene identifying device comprises an image preprocessing module, an image extreme point detecting module, an image characteristic point positioning module, a principal direction determining module, a characteristic extracting module, and a scene determining module. The image characteristic point positioning module is used to determine an extreme point, which is used as a characteristic point, by removing low contrast ratio points of various extreme points sensitive to noises and unstable edge points. The principle direction determining module is used to form a line by connecting any two adjacent peak values in the gradient direction histogram of the characteristic point, and then a plurality of sub-line segments are formed, and the sub-line segments, which are adjacent to each other, and have the similar gradients, are combined together to form one line segment in a length direction, and then the direction of the optimal line segment, which is selected from a plurality of line segments, is used as the principal direction of the characteristic point. The electric vehicle has advantages of high scene identification precision and fast speed.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to an electric vehicle with a scene recognition function. Background technique [0002] If electric vehicles can judge the scene and switch to different driving modes, the efficiency will undoubtedly be greatly improved. However, current electric vehicles do not have a scene judgment function. In addition, in order to process a large amount of image data, it is necessary to improve analysis processing efficiency and accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides an electric vehicle with a scene recognition function. [0004] The object of the present invention adopts following technical scheme to realize: [0005] Provided is an electric vehicle with a scene recognition function for recognizing scenes, including the electric vehicle and a scene recognition device installed on the electric vehicle, the scene recog...
